SLACK-COAL HEATER.

rncrrrcnrron forming part of Letters Patent No. 693,700, dated February18, 1902.

7 Application filed February 8, 1901. Serial No. 46,537. (No model.) i

To ctZZ whom it may concern.-

Be it known that I, EDWIN B. GOSLINE, a

citizen of the United States of America, re-

useful improvements in furnaces, and relates more particularly to themeans employed for dumping the contents of the ash-pit into areceiving-vault located therebeneath.

The invention aims to provide a bottom for the ash-pit formed of two ormore sections, which sections are simultaneously operated from theexterior of the furnace.

With the above and other objects in view the invention consists in thenovel combination and arrangement of parts to be hereinafter more fullydescribed, and specifically pointed out in the claim.

In describing the invention in detail reference is had to theaccompanying drawings, forming a part of this specification, whereinlike numerals of reference indicate corresponding parts throughout bothviews, and in which Figure 1 is a side elevation of my improved furnace,showing in vertical section the fioor above, the furnace being equippedwith my improvements. Fig. 2 is a vertical sectional View of the furnaceproper.

In the drawings the reference-numeral 1 indicates the outer casing ofthe furnace; 2, the combustion-chamber; 3, the inner casing of thefurnace, and 4 the hopper.

The reference-numeral 5 indicates a gooseneck hot-air pipe arrangedwithin the outer casing and communicates with the pipe 6,1eading to thestack,(not shown in the drawings,) and the reference -nnmeral 7represents a damper arranged in said pipe 6.

The reference-numeral 8 denotes hot-air fines leading into the outercasing.

9 indicates the grate-bars, 10 the ash-pit, and 11 the receiving-vaultarranged below the ash-pit.

The reference-numeral 12 indicates the inner door of the furnace, and14the outer door,

arranged in the casing, each of said doors having arranged therein micaor isinglass 15.

16 represents a mirror suitably secured to the outer casing, whichmirror is'so arranged as to deflect against the glass 17, arranged inthe floor 18 of the building. Asuitable opening 19 is likewise arrangedin the floor for the reception of an operating-lever 20, carrying at itsupper end a handle 21, fulcrumed at 22, and having formed at its lowerend a slot 23, in which is pivotally secured an arm 24, carrying shafts25, to which the grate-bars 9 are attached in the interior of thefurnace.

My improved means comprises a reciprocating lever 26, extending upwardlythrough the opening 27, arranged in the floor of the building, and isprovided with a handle 28. The lower end of said lever is bifurcated, asshown at 29, carryinga pin 30,which is adapted to operate in the slot31, formed in the bell-crank lever-32, which lever is pivoted at 33 tothe outer casing 1. The other end of said bellcrank lever islikewiseslotted, as shown at 34, to receive a pin 35 of the lever 36, said levercarrying pins 37, operating in slots 38, formed in the arms 39, saidarms being pivotally secured at 40. These pivots or shafts extendingthrough the casing are fixed at 41 to a pair of trap-doors 42, saiddoors carrying engaging ends 43 to engage and form the floor of theash-pit and are constructed in a manner to engage each other whenclosed.

The reference-numeral 44 indicates an operating-wheel, which is suitablyjournaled on the upper floor of the building. Said operating-wheel uponits shaft carries a sprocketwheel 45, over which passes an endlesssprocketchain 46, operating through an opening 47, arranged in thefloor, and is connected to the sprocket-wheel 48, carrying a shaft 49,extending through the outer casing and through the hopper 4. Upon thiscommon shaft is also keyed a cog-wheel 50, mesh ing with the cog-wheel51, the latter having a shaft 52, as shown. Upon these shafts 50 and 51,extending through the hopper, are arranged toothed wheels 53, whichserve to feed the fuel from the hopper into the combustion-chamber.

The reference-numeral 54 indicates an operating-lever extending throughan opening 55, arranged in the floor of the building, and

. this operating-lever is provided at its upper end with a handle 56 andis fulcrumed at 57 to thevside of the casing 1 and carries at its lowerend a shaft 58, extending through a slot 59, through the outer casing,and to the inner casing 3. This casing 3 is provided with guides 60 toreceive a slide 61, secured to the shaft 58, to operate a damper.

The reference-numeral-62 indicates an operating-cord extending throughan opening 63 arranged through the floor of the building, and carries ahandle 64:, the lower end of said operating-cord being connected at 65to the damper 7, which ishinged at 66 to the pipe 6.

For the purpose of illustrating my invention I have shown the sameoperated from the floor above the furnace; but it will be noted that thesame operation may be accomplished by extending the operating mechanismto the second or third floor above.

In view of the above detailed description it is thought that adetailed'description of the operation is unnecessary, and it will benoted that various changes may be made in the details of constructionwithout departing from the general spirit of my invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

' In a device of the character described, the combination of a casing,an ash-pit, a pair of trap-doors forming the bottom thereof, tonguedengaging faces on opposite sides of said doors adapted to engage and lieflush with one another, shafts secured to each of said trap-doors, areciprocating lever projecting above the floor, a handle secured to theupper end thereof, a bifurcated lower end on said lever, a bell-crankpivotally connected to the casing, said bell-crank having theextremities of its arms slotted, said bifurcated end of said leverhaving one of said arms socured in said bifurcation, a pin engaging saidbifurcated end and operating in said slot, a lever secured transverse tosaid operating-lever, a pin carried by one end of said lever, said pinengaging in the slot formed in the arm of .said bell-crank, arms havingone of their ends rigidly connected to the shaft, the other ends of saidarmsbeing slotted, and pins carried by said lever and adapted to engagein said slots, substantially as described.

In testimony whereof I affix my signature in the presence of tWoWitnesses.

EDWIN B. GOSLINE.
